okay so if i got that right i could plug the sd card reader to another AUX port and change the pins_ramps.h or i solder the connectors to the old sd card reader and change the SDSS (dont know what that is) line

I´m not really getting it what i shall do now, just try to connect both of them but only put the sd card into one reader?
I also want to add some TC2130 driver some day, as far as i know they also communicate through the spi port so how would that work out?

So, one of the guys at my local hackerspace (also) expressed a need for an easy fix for attaching additional things to the AUX-3 (SPI) port, and he wanted to solder as little as possible to his existing boards,and he would like to use only jumper wires.
After some talk, I agreed to design a board that would meet his needs - and as it so happens, might also make things easier for you Kutulu.

This board connects between the RAMPS 1.4 board, and the LCD-wires board.

This board duplicates the AUX-4 port, as well as adds two more AUX-3 ports to your system. You do however get to chose which Ramps 1.4 I/O pins goes to the "D53" and "D49" pins of the added AUX-3 ports.

Using jumper wires, I/O pins from AUX-2 (or unused pins from AUX-4) can be channeled to the D53, D49 pins of the added AUX-3 ports.

I have ordered some of these boards, so you are welcome to have one of them, once they arrive at my location (should happen in 1-3 weeks).
But you might also want to simply order some boards yourself, so I have included the Zip file I have used to order these boards.

That looks interesting, with this board i can use tmc2130 drivers and an external sd card?

Yes, with this add-on board it is almost plug-and-play to do both TMC2130 and external sd card (and LCD sd-card) at the same time.

The TMC2130 needs the SPI signals (MISO, MOSI, SCK) and they are available at one of the extra AUX-3 ports.

The external sd card also needs the SPI signals, as well as a few Arduino I/O pins, for sd_select and sd_detect.

The SD card on the LCD needs the same signals as the extrenal sd card. And with this board it is quite simple to make the two SD card readers share the same Arduino I/O pins for sd_select and sd_detect (for this two solder jumpers needs to be connected), or to arrange for the external sd card to use different Arduino I/O pins for sd_select and sd_detect (just use jumper wires).
